A3000D Boot Issues
« on: April 05, 2021, 10:21:19 AM »
Hi all,

After many years in hibernation I fired up my A3000D the other day. I last booted it a couple of years ago and been sat in my office ever since. First problem I encountered the machine wouldnt boot from the onboard scsi drive. This used to happen but I could resolve it by warm resetting after the drive had spun up. Not this time though. Several warm resets and still no luck.

Got it booting off of floppy though and HDToolbox reported the internal SCSI HD and external SCSI CD Rom. Thought problem was due to bad termination. SCSI chain checked out though. There are no resistor packs on the motherboard. Resistors are present on the HD and the CD Rom is terminated. After much fiddling machine booted in to Workbench off the HD. Hey presto all ok. Set up and configured the Picasso II gfx card. All ok. Installed Z3 fastlane; all ok.

Installed Cyberstorm MK11 68060. And then it went pearshaped. Installed CS libs - new 68040 and 68060 libs in Libs. Started getting cheksum errors when installing OS3.9. Was running 3.1 upto that point.

Stopped booting off SCSI HD. Could still boot into WB off floppy. HDToolbox still reporting scsi devices - HD and CDRom but neither of them being seen when booting from Os3.9 emergency disk.

After alot of googling I removed the RTC clock chip. Removed cyberstorm. Removed Picasso and Z3. Machine booted off floppy but cause OS3.9 install failed wouldnt auto boot off HD. Used HDToolbox and prepped HD again. Seemed ok.

Installed Cyberstorm; Z3 and Picasso. Started to install OS3.9 and gain checksum error. Install failed.

Warm reset. Emergency floppy in drive. Booted then couldnt see HD or CD Rom again.

Removed Cyberstorm; Z3; Picasso; Switched on. Floppy light came on and then Kickstart screen. Insert floppy - WB3.1 install disk. Now wont see the disk. Switch off. Left disk in floppy drive. Switch on - boots to WB but wont detect disk changes or recognise when there is no disk in floppy drive - DF0. Also floppy no longer clocks which makes me think the system is not polling the floppy drive - problem with Denise?

Machine had barrel battery replaced by previous owner. I removed the replacement battery. Area around battery looks okish. Couple resistors look not too good. R469 looks to have corrosion. See pics. Agnes also gets warm - makes me think Ive damaged something when I removed the RTC chip.

Anyone got any ideas as to what the prob could be?

Floppy CHNG signal is read by one of the CIA chips, not Denise.

It could be the drive is no longer sending the signal. Ideally, try with a different drive. Also check the cable (pin 2 is the signal for CHNG).

Your problems seemed to start when adding all your cards, has the power supply ever been replaced or even recapped? Because a failing 12V could have lead to your read/write errors on the system drive.

"Your problems seemed to start when adding all your cards".

Got it sorted! Plugged an old external floppy drive in. Booted off it. DF0:??? showing on workbench. Check the cables plugged into internal drive. There was the problem. I had dislodged the ribbon cable out of the floppy when I had removed the cards.

Now to see if I can get the SCSI working.

Thanks for your help much appreciated.

When dealing with wonky clock/SCSI issues on a 3000, a good first step is SetBatt. Use the amnesia option to clear/reset the settings.

Perhaps it might be best to just install processor card and  then install operating system. Leave the other cards off until after you've got a successful WB3.9 install.

That seems to be the step failing which has conspicuously not been happening. Why doesn't the hard drive like it?

I don't know how you are fixed for capacity but you can have multiple bootable partitions.

Also might be an issue with how you are partitioning the drive maybe. That's what throws the install? 3.1 it's OK but not 3.9.

Cheers Matt.

Ive had a look at that utility. Problem I have is how do I get it onto a 3.5 inch floppy the A300o will read? I can download and unpack using WinUAE and then write to CD on my PC but I cant get the SCSI CD Rom to work to then write it to the 3.5 inch floppy.

I can write it to a USB stick and then use my Deneb card to read it but I cant get the Deneb working till I get the A3000 SCSI drive working to then install Poseidon.

I don't have a PC with a 3.5 inch floppy drive to be able to use cross dos.

Its a bit of a tricky one.

Best.
Weed

Hmmm... OK, if you can get setbatt onto a CD - the issue becomes reading it on the Amiga side.

Is it possible for you to setup a WB 3.1 floppy with z3scsi.device on it, to let you try and mount the scsi CD drive using the Z3 Fastlane controller, to let you access the program on CD and run it to sort out the onboard controller?

I don't know if mounting the hard drive that way is really what you want, what you want is the hard drive being recognized by the onboard scsi controller. But it could be a workaround just to get that program run, and hopefully sort out the onboard controller.

Does this A3000 have real 3.1 ROMs, or is it softbooting Kickstart from original 1.4 ROMs and files stored on the hard drive?

Probably not important. And the Z3scsi.device driver is in the ROM of the card, so you really just need a suitable mountlist entry for CD0 in the devs/dosdrivers drawer of your boot floppy. And a compatible CD filesystem in your L diredctory of the boot floppy. That might just save the day.

A pain in the rear to connect the CD drive that way, but it should work.
